In some natural systems the pH must be maintained within very narrow limits. For example, in human blood the pH must remain close to 7.4 or cell deterioration occurs. Blood contains several weak acid/conjugate base equilibria called buffers which control the pH. One weak acid present in blood is the dihydrogen phosphate ion, H2PO4-1 for which the equilibrium in aqueous solution is:

H2PO4-1(aq) <---------> HPO4-2(aq) + H+1(aq)

0.50 mol H2PO4-1 and 0.50 mol HPO4-2 are in equilibrium in 1L of aqueous solution, the pH of the solution is 7.2. If 0.01 mol of HCl is added to the 1L solution, assuming that all the added H+ ions are used up in the equilibrium shift, calculate the concentration of H2PO4-1(aq) and HPO4-2(aq) and hence the pH of this new solution.

1. In light of the ongoing Covid-19 outbreak, the government has recently imposed the Conditional Movement Control Order (CMCO), which prevents from a gathering of people and limits human physical contact only for doing the necessities, therefore no physical face-to-face classes can be held at Circle College. As there is no information about when these restrictions will be lifted, you are concern about the sustainability of Circle College in the future. You realize that there is an urgent need for Circle College to digitalized business operation and management systems to suit the needs of the current situation.

Suggest FIVE (5) possible solutions (using the concept of e-business, cloud computing or shared services) to improve the efficiency of Circle College’s operation in the current situation by focusing on teaching and learning method, the sharing of the learning resources and the exchange of information amongst all stakeholders. Please list the relevant references to support the discussion for this question.

George has a ticket to see a Syracuse basketball game tonight, but there is a major snowstorm that will make driving very difficult. His wife suggests that he stay home. She reminds him that two weeks ago, he stayed home from going to a basketball game because of similar weather. George replies that the situations are different. He reminds her that he had been given the ticket for the game two weeks ago, but that he had paid $80 for the ticket for tonight’s game. Therefore, he was going to drive to Syracuse to see the game.

Use the concepts of behavioral economics to explain his behavior. Is he acting like an Econ or like a Human? What might explain his decision to go to the game tonight, even though the driving conditions are the same as they were two weeks ago?

Most people have several jobs over their lifetimes. Give a brief description of two or more of the jobs you’ve already had. Without revealing private information, explain if the job was part-time or full-time and address the following questions.

• What skills were required to perform your best?

  • To what extent were agility, problem solving, and technology skills necessary for success?

• What skills did you learn in each job?

  • How did learning these skills contribute to improving your ability to be effective in your work?

• Did these new skills increase your human capital?

• If you haven’t yet had a job, describe the type of career you hope to have after finishing school.

  • How will agility, problem solving, and technology skills be a vital part of your success in this type of career?

You design a microarray experiment to determine the difference in gene expression patterns between normal and cancerous lung tissue from humans. You label the cDNA derived from a lung tumor with a red fluorescent dye and the cDNA derived from normal lung tissue with a green fluorescent dye. You hybridize the cDNA to a microarray chip in which each spot corresponds to a DNA sequence from a different human gene.

a. What can you infer about a particular gene’s expression if it’s corresponding spot fluoresces:

Green?

Red?

Yellow?

Black (no fluorescent signal)?

b. If you were searching for an anticancer drug that would inactivate a protein whose activity contributes to cancer, which of the genes represented on the microarray encode proteins you would most likely chose as a potential target? Green, Red, Yellow, or Black? Briefly explain.

Everything we do on this planet leaves a mark. An ecological footprint is the degree of human impact on our ecosystems. Americans are at the top of the list for their detrimental footprints on our ever-increasing fragile planet. How does your personal footprint compare to others in America or others around the world? Do you personally do things which should help to lessen your footprint? Have you within recent years changed your habits or actions to help the planet? Do you think that global warming and destruction of our planet is severe, or do you think it is all public hype? Are the Earth's forests disappearing? Does it matter if they are? Is there any hope for our planet? What are your suggestions or concerns? List at least one source from your research. MUST BE IN YOUR OWN WORDS.

WORD COUNT 250

Take each of the above individually and provide a specific example of how each are responsible in human motion. Please use specific joints and musculature in the examples.

1. Magnitude of force

2. orientation of force

3. direction of force

4. point of application of the force

5. length of muscle and length/tension relationship

6. velocity of movement and force/velocity relationship

7. Fiber arrangement and fast/slow twitch fiber ratio.

Here are a couple examples:

1. The orientation of force: This refers to the angle between the line of action and the center of the joint. When the angle is between 1 and 90 degrees there will be a stabilizing force. When the orientation is between 91 and 180 degrees, there will be a dislocating force.

2. The magnitude of force: The greater the magnitude of force, the greater will be the ability to overcome greater and greater resistances. This is especially important when longer levers are involved.

Sex education refers to an array of topics that comprise sexuality. Such topics may include contraception, human development, the anatomy and physiology of the reproductive system, and sexual behavior. The teaching of sex education to children has always had a big stigma attached to it, but it is an important topic for young individuals to learn.

For your initial post, address the following:

Research and report on the sex education protocols and regulations in your state.

At what age should children be exposed to sex education topics? What topics should be discussed and why?

Should sex education be mandated as part of the curriculum in public schools? Why?

For your reply post, consider and address the following questions:

Based on the responses of your classmates, what similarities and differences exist between states?

If the subject is mandated, should parents be allowed to exempt their children? Based on this decision, are there public health risks?
